RAILWAY-TIE Specification of Letters Patent.

Patented Aug. 4, 1914.

Application filed December 27, 1913. Serial No. 809,006.

To all whom it may concern:

Be it'known that I, Minion T. ORI'ITEN- DEN, a citizen of the United States, residing at Carthage, in the county of Jasper and State of Missouri, have invented certain new and useful Improvements in Railway lics; and I do hereby declare the following to be a full, clear and exact description of the invention, such as will enable others skilled in the art to which it appertains .to make and use the same.

This invention relates to new and useful improvements in railway ties, and has for its principal object the provision of a tie having a fastening means which will prevent the rail from spreading and thereby causing wrecks and much loss of life. 7

Another object of the invention .isthe provision of a composite tie in which the, re-

silient qualities of the old type of wood tie are retained and combined with the advahtages at present in use of the metallic tic.

A further object of the invention is to provide a novel means for securing the rail in place on the tie and preventing the same from becoming displaced.

With the above and other objects in View, the invention consists in the combination and arrangement of parts which will be fully set forth in the following specification and accompanying drawings in which,

Figure 1 is a top plan view of a railroad tie constructed in accordance with this invention showing the some as it would appear with one of the rails in place, and Fig. 2 is a side View of Fig. 1 showing the same partly in section to clearly illustrate the innor construction thereof.

Referring now to the drawings by charactors of reference, the numeral '1 designates as an entirety, the steel casing forming the principal element in the construction of this tie, and is so shaped as to form a hollow rectangular box in which the concrete filling, indicated by the numeral 2, is ada ted to he placed. A plurality of transverse y extending reinforcing bars 3 are secured at spaced intervals to the side walls of the tie as clearly shown in the drawings, and are adapted tocooperate with the longitudinally extending reinforcing bar 4 to strengthen the concrete and prevent the same from becoming displaced with relation to the casg The body portion 1 of the tie is provided near each end with the slits 5 which form the inwardly extending tongue (3. This tongue 6 is adapted to be bent upwardly as at 7 and bent again angularly as at 8 to form a rail flange cngagin member whiclrholds the outer flange of tie rail firmly in place on the tie. A suitable bolt 9 extends through an aperture in the casing 1 near the inwardly extending tongue 6 and is adapted to receive the nut 10 which cooperates with the casing 1 to firmly hold a clamping member 11 against the inner flange of the rail when the same is in place. i

It will be clearly seen from the foregoing that in use, the tie is placed in the desired position and the outer flange hf the rail slipped beneath the tongue 6. It will be evident that the flange engaging member 11 is then slipped over the end of the bolt 9 and the nut 10 placed thereon, whereupon the same is tightened, and it will be apparent that thcrailwill he firmly clamped between the tongue 6 and the flange engaging member 11 and thereby held from displacement. While in the foregoing I have shown and described the preferred embodiment of my invention, I wish it to be understood that I may make such changes in the combination and arrangement of parts as will fall within the scope of the claim appended.

Having thus described my invention, I claim:

- A rail tie consisting of a rcctangular metallic casing being filled with concrete, a reinforcing rod extending longitudinally throiigh the casing in line with the longitudinal center thereof at a point approximately centrallv thereof, said rod secured at its ends tolthe ends of the casing, transverse rods extending through the casing at points at the center and adjacent to the ends thoreof and rail clamping means formed upon the upper face of the casing.

In testimony whereof l allix my signature in presence of two witnesses.
